DETAILED DESCRIPTION

Described herein are objects, such as beverage containers, with low power electronic devices (e.g., electronic display devices) that include wireless modules that use multiple wireless protocols to efficiently communicate with computing devices (e.g., mobile computing devices). As used herein, a low power electronic device is an electronic device that runs on a battery and that typically does not have access to frequent charging. Thus, low power electronic devices are devices for which battery life conservation may be important, and which may be optimized to extend battery life. The low power electronic devices may also be standalone devices that are not attached to beverage containers (e.g., bottles) or other objects. The electronic devices use a first low energy unidirectional wireless protocol (e.g., the iBeacon® protocol or other Bluetooth® low energy (BLE) protocol) to transmit information usable to identify the electronic devices. The electronic devices additionally use a second higher energy bidirectional wireless protocol (e.g., a Bluetooth protocol) to establish wireless connections with computing devices (e.g., mobile computing devices). The low power electronic device may not be connected to a network (e.g., may not include a Wi-Fi network adapter or modem), and may rely on another computing device to act as a proxy for communication with a cloud based service. The cloud based service may include logic for controlling the low power electronic device, granting access to the electronic device, and so on. By using a low energy wireless protocol such as iBeacon to broadcast an identity of the low power electronic device and using a higher energy wireless protocol such as Bluetooth to establish connections to those mobile computing devices that satisfy criteria, energy usage of the low power electronic device may be minimized and battery life may be maximized.

Also described herein are an electronic device controller application that executes on a mobile computing device and an electronic device management service that runs on a server computing device. The electronic device controller application may receive data (e.g., a unique identifier) from low power electronic devices and forward such data to the electronic device management service for processing. The electronic device controller may act as a proxy (e.g., an Internet proxy) for the low power electronic device, which may not have a capability to access the Internet or remote services.

There are shown in the drawings and will herein be described in detail several specific examples with the understanding that the present disclosure is to be considered as an exemplification of the principles of the described technology and is not intended to limit the technology to the examples illustrated.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It will be understood that like or analogous elements and/or components, referred to herein, may be identified throughout the drawings with like reference characters. It will be further understood that several of the figures are merely schematic representations of embodiments of the present technology.

Embodiments are discussed herein with reference to electronic display devices that are mounted to or embedded in a container or bottle. However, embodiments also cover other types of electronic devices that mount to or are embedded in a container. Such other electronic devices may rely on displays of computing devices (e.g., of mobile devices carried by users) to display messages. Accordingly, it should be understood that discussion of electronic display devices herein also applies to other types of electronic devices that do not have displays. Additionally, embodiments also apply to standalone electronic devices that do not attach to any specific containers or other objects. Additionally, embodiments are discussed with reference to low power electronic devices. However, it should be understood that embodiments also apply to other types of electronic devices (e.g., higher power electronic devices).

Referring to the figures, FIG. 1 is a diagram depicting an example system architecture 100 for a low power electronic display device 135 integrated with an object 105 and wirelessly connected to a mobile computing device 110, in accordance with an embodiment of the present disclosure. Object 105 may be a container such as a bottle, box, cup, package, etc. that includes a cavity or recess shaped to receive the low power electronic display device 135. Accordingly, the electronic display device 135 may be shaped to fit into the cavity or recess. The object may also be other types of objects, such as a vehicle, wall, hat, etc. that includes a cavity shaped to receive the low power electronic display device 135. In the illustrated example, the object 105 is a glass bottle for alcoholic beverages.

The low power electronic display device 135 is attached to the object (e.g., mounted in the cavity shaped to receive the low power electronic display device 135). Low power electronic display device 135 may be attached to object 105, such that it appears to be integrated with the object 105. In one example, the low power electronic display device 135 may utilize an attachment mechanism (e.g., clip, magnets, adhesive) to attach to object 105 while the object is in use or on display. The electronic display device 135 may be detached from the object 105 via the attachment, such as for use on another object. For example, electronic display device 135 may be attached to a beverage container while the beverage container contains fluid. However, once the beverage container is empty, electronic display device 135 may be removed from the beverage container and temporarily attached to another object.

In some examples, electronic display device 135 may be a device that conforms to the shape of the object 105 and attached thereto, such as by wrapping or snapping onto the object (e.g., a bottle). Such an electronic display device 135 may adapt to any shape or size of container or other object. Optionally, such an electronic display device 135 may have a flexible screen or include a flexible image film technology to wrap around or as a “sleeve” to any object or container or product wrapper. For example, the electronic display device 135 may include a module with active components (e.g., LEDs, processing device, memory, battery, etc.) that is connected to a sleeve that can fit around a bottle. The sleeve may be plastic, polymer, rubber, or other flexible material. The sleeve may stretch to conform to the shape of the object that it is fit around. Optionally, portable displays may be interchangeable between objects and be associated with the object it is attached to. Other embodiments may include an electronic device molded or printed onto the outer surface of the object or embedded within the material of the object. Such an electronic device may include a display that is visible when viewing the object. The electronic device may be powered using a power source, such as a battery, solar cells, or other similar power sources.

The low power electronic display device 135 includes a wireless module that periodically broadcasts a low power radio signal 125. The low power radio signal may be broadcast every second, every 2 seconds, every half second, every 10 seconds, or at some other interval. The low power radio signal may be transmitted using a protocol such as Bluetooth low energy (BLE) or iBeacon, and may include a unique identifier assigned to the low power electronic device 135. In one embodiment, the unique identifier includes a universally unique identifier (UUID) that identifies an original equipment manufacturer (OEM) of the electronic display device 135, a first assigned numerical value and a second assigned numerical value. If the iBeacon protocol is used, the low power radio signal 125 includes the UUID, a major and a minor, where the major and minor are each 2 byte values.

A mobile computing device 110 executing an electronic device controller application (not shown) may enter a range of the low power electronic device 135 and receive the low power radio signal. The mobile computing device 110 may be a mobile phone, a tablet computer, a laptop computer, a portable game console, a digital camera, or other computing device. The electronic device controller application (App) may be configured for communicating with low power electronic devices of the OEM, and may include a user interface that enables a user of the mobile computing device 110 to control such low power electronic display devices 135.

The mobile computing device 110 may establish and/or maintain a wireless connection with a wireless carrier and/or with a local area network (e.g., via a wireless access point attached to the local area network). Through the wireless connection to the wireless carrier or local area network (LAN), the mobile computing device may establish and/or maintain a connection to an electronic device management service 120. Responsive to receiving the low power radio signal, the mobile computing device 110 may generate a query that includes the received unique identifier (or a portion thereof, such as the major and minor) and information that identifies a user of the mobile computing device. The information that identifies the user of the mobile computing device may be user account information of a user logged into the electronic device controller application. The mobile computing device 110 may also determine its current location (e.g., latitude and longitude) and include the current location in the query. The mobile computing device 110 may then transmit the query to the electronic device management service 120 via the connection 132.

Electronic device management service 120 processes the query to determine whether the user has permission to access the low power electronic device and/or to determine whether any actions should be taken. In one embodiment, the electronic device management service 120 determines whether the user has permission to access the low power electronic display device 135 and sends a response to the mobile computing device 110 indicating whether the user has such permission. If the user has permission to access the low power electronic device 135, then mobile computing device 110 notifies the user of the presence of the low power electronic display device 135. Such notification may be performed by displaying an identity (e.g., assigned name) of the low power electronic device 135 in a display of the mobile computing device 110, triggering a haptic feedback module, generating an audio alert, and so on.

Bluetooth devices generally broadcast a small amount of information about themselves to allow them to be discovered. The broadcast information lets other applications and devices know the basic category of a Bluetooth device. However, there are no standards for broadcasting and discovering other information about a Bluetooth device. Given the large numbers of Bluetooth devices that may be found in an area (e.g., cell phones, computers, wireless keyboards, wireless mice, wireless headsets, etc.), it may be very cumbersome and time consuming for one Bluetooth device to discover a specific other Bluetooth device.

In embodiments, by combining the periodically broadcast low energy radio signal (e.g., iBeacon signal) with access to a back-end electronic device management service 120, the mobile computing device 110 is able to quickly determine which low power electronic devices of interest (e.g., those manufactured by a particular OEM) are nearby without having to connect to every Bluetooth-enabled device and read its characteristics. This may reduce discovery time for Bluetooth devices from minutes down to seconds.

Once mobile computing device 110 receives notification that the user has access to the low power electronic display device 135, mobile computing device may present multiple command options for controlling the low power electronic display device 135 via the user interface of the electronic device controller application. Such command options may include options to generate a message, send the message to the low power electronic display device 135, cause the low power electronic display device to display the message or another message already stored on the low power electronic display device, receive a battery level indication from the electronic display device, remotely power down the low power electronic display device 135, and so on. Mobile computing device 110 may additionally establish a wireless connection 130 (e.g., using a bidirectional wireless communication protocol such as Bluetooth), and may send commands and/or messages to the low power electronic display device 135 via the wireless connection 130. For example, a user may type in the display message 140 “HAPPY HOLIDAYS” via the user interface and may then send the display message 140 to the low power electronic device 135 for display thereon.

As described above, the combination of a periodic low energy radio signal with basic device information (e.g., a unique identifier) and a back-end electronic device management service enable quick discovery of low power electronic devices in an area. This combination of the periodic low energy radio signal with basic device information and a back-end electronic device management service to identify the low power electronic devices based on the device information also enables groups of specific devices to be updated or controlled in seconds, regardless of how large the group of electronic devices and how many other Bluetooth-enabled devices are in the area. In prior systems the process of updating a group of Bluetooth-enabled devices would typically involve discovering every Bluetooth-enabled device in an area, iterating through all of the discovered devices and interrogating those devices for their characteristics to determine whether they belong in the desired group. This process would take a large amount of time, especially if many of the low power electronic devices were present and enabled in the same area, such as at a bar or retail store.

In one embodiment, the low power electronic display device 135 may not be owned by the user of mobile computing device 110. Responsive to electronic device management service 120 receiving the query from mobile computing device 110, electronic device management service 120 may determine an owner of the low power electronic display device 135, and may send a notification to that user (e.g., via email, text message, etc.). The notification may indicate an identity of the user of the mobile computing device 110 and/or a location of the low power electronic display device 135. Alternatively, electronic device management service 120 may log the query, and the owner may use a computing device 145 to connect to the electronic device management service 120 (e.g., via a Web browser), and may view the log.

In some instances, the owner of the low power electronic display device 135 may use the computing device 145 to provide an instruction to the electronic device management service 120 for controlling the low power electronic display device 135. The electronic device management service 120 may then send an instruction to the mobile computing device with a command to forward the instruction on to the low power electronic display device 135. In some embodiments, this may be performed even if the user of the mobile computing device 110 does not have access to the low power electronic display device 135.

FIG. 2 is a block diagram depicting an example system architecture 200 including a low power electronic device 210, one or more computing devices 226, and a server computing device 250. In one embodiment, system architecture 200 corresponds to system architecture 100 of FIG. 1. Low power electronic device 210 may be communicably coupled to the one or more mobile computing devices 226 via wireless connections. As discussed above, these wireless connections (e.g., Bluetooth connections) may be established responsive to server computing device 250 determining that the mobile computing devices 226 have permission to access the low power electronic device 210. In one example, low power electronic device 210 may be a portable display associated with or a part of (e.g., integrated into) an object, such as a beverage container. Alternatively, an electronic device that does not include a display and/or that is not attached to any other object may be used.

Low power electronic device 210 may include a display module 212, a sensor module 214, a wireless module 216, a processing device 218, a memory 220, and/or other hardware, firmware and/or software modules. Memory 220 may store an assigned unique identifier 222 of that identifies an OEM associated with the low power electronic device and uniquely identifies the low power electronic device 210 of that OEM. Memory 220 may additionally store one or more messages 224 that may be displayed by display module 212. In one embodiment, memory 220 also stores a password. In one embodiment, one or more of the wireless module 216, processing device 216 and/or memory 220 are components of a system on a chip (SoC).

Display module 212 may include an electronic visual display that may be illuminated to display an image or alphanumeric message. The image or alphanumeric message may be static or may be displayed in a manner that appears to show movement (e.g., motion picture or scrolling text). The electronic visual display may include light emitting diodes (LEDs), organic light emitting diodes (OLEDs), liquid crystal display (LCD), or other similar display technology. Display module 212 may have a variety of sizes and include pixels of various colors. In one example, display module 212 may cover a portion of an object's exterior face or the entire exterior face of the object in all angles (0 degrees to 360 degrees).

In one example, display module 212 may be used for advertising or displaying various images or messages, such as greetings, calendar events (e.g., birthdays, anniversaries, holiday messages, events of cultural significance), etc. Optionally, the display module 212 may utilize animated images or messages. For example, messages may scroll from any direction, strobe, glow, etc. The messages or images may allow objects holding the low power electronic devices to serve as an advertising or marketing channel. The marketing channel may allow for multiple levels of distribution (e.g., directly to customers, through a distributor, etc.). A customizable communication or message allows for maximum flexibility.

Sensor module 214 may include one or more sensor devices for gathering data associated with the object and/or low power electronic display device 210. The sensor devices may include audio sensors (e.g., microphones), motion sensors (e.g., accelerometer, gyroscope, etc.), fluid measuring sensors (e.g., mechanical gyrator), lights sensors (e.g., ambient light sensor), location sensors (e.g., global positioning system sensors (GPS)), temperature sensor (e.g., thermometer), or other similar sensing devices. Data generated by sensor module 214 may be forwarded by mobile computing devices 226 to server computing device 250 for processing. For example, an audio signal may be sent to server computing device 250 to perform speech to text processing.

Wireless module 216 may enable low power electronic device 210 to receive and transmit messages and commands. Wireless module 216 may include a transmitter, receiver, transceiver, memory, antenna, and so forth for communicating with a computing device (e.g., with mobile computing devices 226). In one embodiment, wireless module 216 includes a Bluetooth wireless adapter capable of communicating using multiple different Bluetooth based protocols. Alternatively, wireless module 216 may include a wireless adapter that uses protocols for Near Field Communication (NFC), Wi-Fi®, infrared (IR), Linux® wireless, Zigbee®, any other low frequency RF modulation, microwave, radar, or other similar connections.

Wireless module 216 may be used to initiate or establish wireless connections to mobile computing devices 226. The connections may include direct connections and indirect connections. Direct connections may directly connect low power electronic device 210 with a mobile computing device 226 and may not use any intermediate networking elements (e.g., access point, router, switch, hub) to connect the devices. This may be implemented using a wireless technology such as Bluetooth, Peer-to-Peer Wi-Fi, or infrared. An indirect connection may include multiple connections, a network 242 or multiple networks.

In one embodiment, when wireless module 216 receives a connection request from a mobile computing device 226, wireless module 216 checks for a password included in the connection request. Wireless module 216 checks the received password against a stored password in the memory 220. If the passwords match, then wireless module 216 permits a wireless connection to be established. If the passwords fail to match, then no connection may be established. Thus, in embodiments the lower power electronic device 210 may only accept application programming interface (API) requests that are sent with the correct password.

In one embodiment, the low power electronic device 210 includes two buttons usable for basic control of the electronic device. The two buttons may include a power button, which may be used to turn on and off the low power electronic device. In one embodiment, the power button is usable to toggle through different modes of operation for the low power electronic device 210. The modes of operation may include an unpowered mode, a sleep mode in which most of the components of the low power electronic display are unpowered (e.g., in which no radio signals are broadcast and a display is disabled), a display state in which a message is displayed by the display module 212 and the wireless module periodically transmits a low power radio signal, and/or a broadcast mode in which the display module 212 is unpowered but the wireless module broadcasts the low power radio signal at an interval.

Mobile computing devices 226 may be any portable devices capable of communicating with low power electronic device 210 that include an electronic device controller application 230 installed thereon. Examples include smart phones, tablet computers, laptops, etc.

Mobile computing devices 226 may include a listening module 228 and the electronic device controller 230. Listening module 228 may run in a background of mobile computing devices 226 and may listen for low energy radio signals that include a unique identifier 222 of any low power electronic device 210 manufactured by a particular OEM. Such low energy radio signals may be short range signals that are periodically broadcast by the wireless module 216. Responsive to receiving such a low energy radio signal, listening module 228 may load electronic device controller application 230. Alternatively, listening module 228 may perform other operations such as generate a query and send the query to the server computing device 250.

In one embodiment, electronic device controller application 230 is a program (e.g., an App) that runs on mobile computing devices 226. In one example, electronic device controller application 230 may be a downloadable application for a mobile device. For example, mobile devices may include Android®, iPhone®, or Blackberry® devices capable of running a software application (e.g., Android Smart Bottle software App, iPhone Smart Bottle software App, Blackberry Smart Bottle software App, etc.). Alternatively, electronic device controller application 230 may be firmware and/or a hardware logic on a mobile computing device 226. Electronic device controller application 226 acts both as a controller for low power electronic devices (which may lack their own user interfaces) and as a proxy for providing network connectivity (e.g., an Internet connection) to the low power electronic devices 210. In one embodiment, electronic device controller application 230 includes a user interface 232, a device connecting module 234 and a proxy module 236.

Proxy module 236 communicates with electronic device management service 251 on behalf of low power electronic devices. Proxy module 236 may establish a connection to electronic device management service 251 on server computing device 250 via network 242. Network 242 may include a public network (e.g., the Internet), a private network (e.g., a local area network (LAN) or wide area network (WAN)), or a combination thereof. Network 242 may also include a wired network (e.g., Ethernet network), a wireless network (e.g., an 802.11 network or a Wi-Fi network), a cellular network (e.g., a Long Term Evolution (LTE) network), or combination thereof, and may include a wireless access point, network routers, switches or other similar network devices.

Responsive to mobile computing device 226 receiving data from low power electronic device 210 (e.g., a unique identifier received in a low energy radio signal), proxy module 236 may forward that data to server computing device 250 for processing by electronic device management service 251. Proxy module 236 may generate queries and/or other messages for electronic device management service 251, which may include the data received from the low power electronic device as well as other data generated or received by mobile computing device 226. Data from the low power electronic device 210 may include a unique identifier assigned to the low power electronic device 210, a battery state of the low power electronic device, messages stored on the low power electronic device, acceleration data, speech data, rotational data, proximity sensor data, light sensor data, temperature data, and so on. Data from the mobile computing device 226 may include location data, user account data, date and time, signal strength data (e.g., of the low energy radio signal received from the low power electronic device 210), and so on.

Electronic device management service 251 may include a rules engine 254 (discussed further below) that processes received data to determine whether any actions are to be taken. Proxy module 236 may then receive a response message from the electronic device management service 251 based on an output of the rules engine 254. For example, proxy module 236 may receive an indication as to whether the user of the mobile computing device has permission to access the low power electronic device 210. Proxy module 236 may additionally receive messages to be displayed to the user via user interface 232 and/or instructions to send messages and/or commands to the low power electronic device 210. Such messages and/or instructions may be sent to the low power electronic device 210 whether or not the user has access to the low power electronic device. For example, if the user does not have access to the low power electronic device 210, then such messages and/or commands may be sent to the low power electronic device without notifying the user of the mobile computing device of the presence of the low power electronic device or the fact that the mobile computing device 226 is communicating with the low power electronic device 210.

User interface 232 acts as a remote user interface for low power electronic device 210. User interface 232 may be a graphical user interface or a command line user interface. If a user of the mobile computing device 226 has access to the low power electronic device 210 (decided by electronic device management service 251), then the user interface may display a presence of the low power electronic device 210 as well as command options for controlling the low power electronic device 210.

One example command option includes a command to generate a new message and/or send the new message to the low power electronic device 210. If a user selects a generate message option, user interface 232 may present a virtual keyboard with alphanumeric characters that the user may type on to create a new message. Alternatively, a user may speak into a microphone of the mobile computing device 226, and electronic device controller application 230 may generate an audio file and transmit the audio file to electronic device management service 251 or a separate transcription service to translate the speech into text. The text may then be sent back to the mobile computing device 226 and used for the message. Alternatively the mobile computing device 226 may include a local transcription module that translates speech to text for a new message. Once the new message is created, the user may select a set message command option and select one or more low power electronic devices to send the message to.

Other command options include a display message command, a report messages command, a set unique identifier command, a disable display command, a read battery level command, a read display state command, a change broadcast rate command, and so on. The display message command causes a selected low energy electronic device to display a selected message, which may already be stored on the low energy electronic device or may be sent to the low power electronic device for display.

The set unique identifier command changes a value of a unique identifier assigned to the low power electronic device. Low power electronic devices may be manufactured with a default identifier, and that identifier may be replaced with a unique identifier after the low power electronic device is powered on by a user for a first time. In one embodiment, the unique identifier is a pair of integers (e.g., a major and a minor as defined by the iBeacon protocol). These numerical values in one embodiment are each 2 byte values. The two numerical values may be combined to create a single larger numerical value (e.g., a 4 byte numerical value). By combining, for example, two independent 2 byte values, each of which has 65,536 possible unique values into a single unique 4 byte value, the number of possible unique values is increased many times to 4,294,967,296 possible values.

The report messages command may cause the low power electronic device to notify the electronic device controller 230 of all messages currently stored on the low power electronic device. The low power electronic device may broadcast a low energy radio signal on a periodic basis to notify nearby mobile devices of its identity. The change broadcast rate command may be used to adjust the frequency at which the low power radio signal is broadcast. A less frequent broadcast may improve a battery life of the low power electronic device.

Device connecting module 234 is responsible for establishing wireless connections to low power electronic devices (e.g., to low power electronic device 210). In one embodiment, device connecting module 234 establishes a direct bidirectional peer-to-peer connection to the low power electronic device (e.g., a Bluetooth connection). Alternatively, device connecting module 234 may establish an indirect connection to the low power electronic device (e.g., a Wi-Fi connection to a local area network (LAN) that the low power electronic device is also connected to.

In one embodiment, device connecting module 234 establishes a wireless connection to the low power electronic device responsive to determining that a user of the user device has permission to access the low power electronic device. Such a determination may be made in response to mobile computing device 226 receiving a response from electronic device management service 251 indicating the permission. Alternatively, or additionally, electronic device controller application 230 may cache information on the unique identifiers that the user has permission to access. Responsive to receiving a low power radio signal broadcast by low power electronic device 210, electronic device controller application 230 may compare the received unique identifier to cached unique identifiers. If the received unique identifier matches a cached unique identifier, then electronic device controller application 230 may determine that the user has permission to access the low power electronic device 210 without waiting for a response from electronic device management service 251.

In another embodiment, device connecting module 234 may wait until an instruction to send a command to the low power electronic device 210 is received via the user interface (from a user) or from electronic device management service 215. Responsive to receiving such an instruction, device connecting module 234 may establish the wireless connection to low power electronic device 210. By waiting to establish the wireless connection until data is to be exchanged with the low power electronic device 210, a battery life of the low power electronic device may be conserved.

Server computing device 250 may be a desktop computer, rackmount server, blade server, or other physical machine used to host a server. Server computing device 250 hosts electronic device management service 251. In one embodiment, server computing device 250 includes a virtual machine monitor (also referred to as a hypervisor) that hosts virtual machines, and the electronic device management service is a service that executes in a virtual machine hosted by the server computing device 250. For example, electronic device management service 251 may be a cloud based service that is hosted by Amazon's® Elastic Compute Cloud (EC2).

Electronic device management service 251 is a service for managing the interaction with low power electronic devices and/or other electronic devices. Electronic device management service 251 may include a rules engine 254, an authorization module 256 and/or a messaging module 258. Alternatively, the functionality of one or more of the rules engine 254, authorization module 256 and/or messaging module may be combined into a single module or divided into additional modules.

Authorization module 256 is responsible for determining whether a user of a mobile computing device 226 is authorized to access a low power electronic device. Electronic device management service 251 may receive a query from a mobile computing device 226 (e.g., from a proxy module 236), the query including a unique identifier of a low power electronic device and user account information of a user of the mobile computing device. Authorization module 256 may perform a lookup on the user account and the unique identifier, which may be stored in a data structure (e.g., a database, table, etc.) including assigned unique identifiers 262 and user accounts 264. A user may have access to a low power electronic device if that user owns the device or if access to the device has been shared with the user (e.g., by the owner). If the user account has access to the low power electronic device associated with the received unique identifier, then messaging module 258 sends a response message back to the mobile computing device 226 indicating that the user has access permissions. Otherwise the messaging module 258 may send a response indicating that the user does not have such access permissions.

In some instances a low power electronic device may have a default unique identifier, and may not be associated with any user account. When a query that includes such a default identifier is received, authorization module 256 may determine an unused unique identifier, and may assign that unused unique identifier to the low power electronic device. Authorization module 256 may generate an ownership record for the user account associated with the received query, where the ownership record includes the unique identifier. Messaging module 258 may transmit a response to the mobile computing device 226 from which the query was received, where the response includes the assigned unique identifier. The response may also include an instruction to program the low power electronic device to have the unique identifier. The electronic device controller application 230 of the device connecting module 234 may then connect to the low power electronic device (if a connection has not already been established), and may send an instruction to the low power electronic device to overwrite the default identifier with the assigned unique identifier.

Once ownership of an electronic device is associated with a user, that user may share ownership of the electronic device with other users. In one embodiment, the owner merely provides an address of the additional user (e.g., via the user interface 232 of an electronic device controller application 230 or a web interface provided by the electronic device management service 251). Messaging module 258 then sends an offer email that includes a hyperlink to a location from which the electronic device controller application may be downloaded. Once the recipient downloads and installs the electronic device controller application onto their computing device (e.g., onto a mobile computing device), that user may access the electronic device and perform actions such as set, modify and display messages on that electronic device as if it was their own. At any time an owner may revoke access privileges to an electronic device or a user with which access has been shared may terminate access privileges.

Data from received queries may also be input into rules engine 254. Rules engine 254 may include one or more rules, and may apply these rules to generate commands, perform actions, and/or generate messages based on received data. Actions that are performed may include sending messages and/or notifications to specific users (e.g., to owners), sending messages to mobile computing devices for presentation thereon, sending commands to mobile computing devices that cause them to connect to low power electronic devices and send or forward commands to those low power electronic devices (e.g., to display a message on a low power electronic device), and so on. In one embodiment, authorization module 256 is a component of rules engine 254, and is implemented via an authorization rule and/or a new device rule. Rules engine 254 may include any number of rules, which may be used to perform many different actions. Some example rules and resultant actions are provided, but should not be construed as limiting the scope of the rules engine.

A first example rule is an owner notification rule. The owner notification rule may cause the rules engine to generate a notification which messaging module 258 sends to an owner of an electronic device if a mobile device belonging to someone other than the owner comes within range of the electronic device. For example, when a mobile computing device 226 executing an electronic device controller application 230 comes within range of the low energy radio signal broadcast by low power electronic device 210, that electronic device controller application 230 may generate a query and send the query to electronic device management service 251. The query may include the unique identifier of the low power electronic device, user account information associated with the mobile computing device 226 and a location of the mobile computing device (e.g., as determined via a global positioning system (GPS) receiver in the mobile computing device).

Rules engine 254 may apply the owner notification rule, and may determine that the user account is not for an owner of the low power electronic device 210. Messaging module 258 may then generate a notification that the mobile computing device is near the low power electronic device and that the low power electronic device is at the location, and send the notification to the owner. The notification may be sent by posting it to a social network account of the owner, by sending an email to an email address of the owner, by sending a text message to a phone number of the owner, or by other means. For example, the notification may be sent to a computing device 240 of the owner, which may be a mobile computing device that includes an instance of the electronic device controller application and/or a web browser 244. If the computing device 240 does not include the electronic device controller application 230, then a user of the computing device 240 may use the web browser to access a web page provided by electronic device management service 251. The web page may indicate users who have come within range of low power electronic devices owned by the user, the times of such encounters, locations of those low power electronic devices, and so forth.

Responsive to receiving a notification, a user may send a response back to electronic device management service 251. The response may include a command to send a message to the electronic device, a command to send a message to the mobile computing device and/or a command to perform another action. The electronic device management service 251 may then perform the action in accordance with the command in the response.

A second example rule is a customer welcoming rule. In one embodiment, electronic device management service 251 receives a query from a mobile computing device of a user who does not own a low power electronic device 210. The query may include the user account information of the user of the mobile computing device and the unique identifier of the low power electronic device 210. Rules engine 254 may apply the customer welcoming rule, and determine that the mobile computing device is not associated with an owner of the low power electronic device 210 and came within range of the low power electronic device 210 during business hours. Responsive to such a determination, rules engine 254 may cause messaging module 258 to generate a personalized message welcoming the individual having the user account. Messaging module 258 may send this personalized message to the mobile computing device 226 with an instruction for the personalized message to be displayed on the mobile computing device and/or to be forwarded to the low power electronic device 210 and displayed thereon. For example, the message may be a personalized message that welcomes a user associated with the user account to a bar or other establishment that owns the low power electronic device 210. The message may also be a personalized advertisement or other personalized message.

In some instances low power electronic devices may be logically divided into one or more groups, and a user may select a group to send a message and/or command to. A user with access to multiple electronic devices may generate any desired groupings and/or hierarchical structure of groupings for controlling the electronic devices. This enables the user to easily select a set of electronic devices and perform the same action with regards to each of these electronic devices. For example, a user may generate a top level group for all of the electronic devices in a store, and different second level groups for each floor of the store. The user may then select the top level group to select all electronic devices in the store, or one of the second level groups to select all of the electronic devices on one of the floors.

FIGS. 3-5 depict flow charts of multiple illustrative examples of methods 300, 400, 450 and 500 (hereafter “methods”) for controlling a low power electronic device using a mobile phone and/or remote server. The methods and each of their individual functions, routines, subroutines, or operations may be performed by processing logic of an electric display device (method 300), mobile computing device (methods 400, 450) or server computing device (method 500) executing the method. The processing logic may include hardware, software, firmware, or a combination thereof. For example, processing logic may include a general purpose and/or special purpose processor that executes instructions for performing the methods.

Referring to FIG. 3, at block 305 of method 300 processing logic of a low power electronic device such as an electronic display device or electronic tag periodically broadcasts a low energy radio signal that includes a unique identifier. The periodic broadcast may be generated in accordance with a first wireless protocol, such as a Bluetooth low energy (BLE) protocol or the iBeacon protocol. At block 310, processing logic determines whether a connection request has been received. If a connection request is received, the method continues to block 315. Otherwise, the method returns to block 305.

At block 315, processing logic determines whether a requestor of the connection satisfies one or more security criteria. In one embodiment, processing logic determines whether the connection request includes a password that matches a password that is stored on the low power electronic device. If the passwords match (or other security criterion is met), the method continues to block 320. Otherwise, the method returns to block 305.

At block 320, processing logic establishes a wireless connection to the requestor. This wireless connection may be established in accordance with a second wireless protocol. In one embodiment, the wireless connection is a bidirectional peer-to-peer Bluetooth connection established in accordance with the Bluetooth protocol.

At block 325, processing logic receives a message from the requestor. At block 330, processing logic stores the message. At block 335, processing logic may display the message. In one embodiment, the message is displayed responsive to an additional command from the requestor to display the message.

At block 340, processing logic may receive an additional command to perform some other action. At block 345, processing logic executes the command and performs the action. The command may be configured in accordance with an API of the low power electronic device. Examples of commands include commands to report a battery level, commands to turn on, turn off or change a current mode of operation, and so on. In some instances, the low power electronic device may include onboard sensors such as temperature sensors, sensors that detect a volume or amount of contents of a container to which the low power electronic device is attached, motion sensors, light sensors, proximity sensors, and so on. In such an instance, additional commands may be commands to report on any such sensor measurements.

Referring to FIG. 4A, at block 402 of method 400 processing logic of a mobile computing device executing a listener module waits for a low energy radio signal. At block 405, processing logic receives a low energy radio signal that includes a unique identifier of an electronic device. The unique identifier may include a UUID and a pair of numerical values that combine to form a unique value. If an electronic device controller application is not active, processing logic may check a UUID included in the radio signal at block 406 to determine if the electronic device is of a type that the listener module is listening for. If the UUID matches a stored UUID (e.g., corresponds to a particular OEM), then processing logic may load an electronic device controller application at block 408. If the UUID does not match a stored UUID, then the method returns to block 402.

At block 410, processing logic generates a query including the unique identifier (e.g., including the two numerical values), a location of the mobile computing device and an identification of a user of the mobile computing device (e.g., user account information). At block 415, processing logic sends the query to a device management service running on a server computing device.

At block 420, processing logic receives a response from the server computing device. At block 425, processing logic determines from the response whether the user has permission to access the low power electronic device. If the user does not have such access, the method returns to block 402, and does not notify the user of the presence of the low power electronic device. If the user does have permission to access the low power electronic device, the method continues to block 430.

At block 430, processing logic notifies the user of the presence of the low power electronic device and provides control options for controlling the device. The notification and control options may be displayed via a graphical user interface on the mobile computing device. At block 435, processing logic receives a user command to access the electronic device. The command may be a command to send a message to the electronic device, to retrieve information from the electronic device, to change a mode of the electronic device, and so on. At block 440, processing logic establishes a wireless connection to the electronic device (e.g., a Bluetooth connection). At block 445, processing logic sends a command to the electronic device via the wireless connection to cause the electronic device to perform the desired action. The method may then end, or the user may provide additional user commands for further execution.

Referring to FIG. 4B, at block 452 of method 450 processing logic of a mobile computing device receives a low energy radio signal that includes a unique identifier of an electronic device. At block 454, processing logic generates a query including the unique identifier, a location of the mobile computing device and an identification of a user of the mobile computing device (e.g., user account information). At block 460, processing logic sends the query to a device management service running on a server computing device.

At block 462, processing logic receives a response from the server computing device. At block 464, processing logic determines whether the response includes an instruction for the electronic device. If not, the method may proceed to block 425 of method 400. If the response does include an instruction for the electronic device, the method continues to block 470.

At block 470, processing logic determines whether a user of the mobile computing device has permission to access the low power electronic device. If so, the method continues to block 472, and processing logic notifies the user of the presence of the electronic device and provides control options. If the user does not have access permission, the method proceeds to block 474.

At block 474, processing logic establishes a wireless connection to the electronic device. At block 476, processing logic sends an instruction to the low power electronic device via the wireless connection. At block 478, processing logic determines whether a response has been received from the electronic device. If a response is received, the method continues to block 480, and the response is forwarded to the device management service. If no response is received, the method continues to block 482, and processing logic waits for an instruction to terminate the connection. Alternatively, processing logic may automatically terminate the connection after a predetermined time period (e.g., after 2 seconds, 5 seconds, etc.) if no additional instructions are received.

Referring to FIG. 5, at block 505 of method 500 processing logic of a server computing device receives a query from a mobile computing device. The received query may include an identifier of a low power electronic device and information identifying a user of the mobile computing device. The identifier may include two numerical values (e.g., a 2 byte major and a 2 byte minor). The query may additionally include additional information such as a location of the mobile computing device, a time stamp, and so on.

At block 510, processing logic determines an identity of the electronic device based on the identifier. The identifier may include two numerical values that are concatenated into a single larger numerical value to increase the total number of possible unique values.

At block 515, processing logic determines whether the received identifier is a default identifier. In some instances the identifier may be a default identifier, which may indicate that the electronic device is new. If the identifier is a default identifier, the method proceeds to block 550. Otherwise the method continues to block 520.

At block 550, processing logic determines an unused unique identifier and assigns the unique identifier to the low power electronic device. This may include determining a first numerical value and a second numerical value that can be concatenated to form the single larger value. At block 555, processing logic records a user of the mobile computing device as an owner of the device having the unique identifier. At block 560, processing logic instructs the mobile computing device to program the electronic device to have the unique identifier.

At block 520, processing logic uses data from the query (e.g., the location, unique identifier, user account information, etc.) as an input into a rules engine to determine actions to perform. For example, processing logic may apply one or more rules, such as an authorization rule, a notification rule, etc. At block 525, processing logic may apply an authorization rule to determine whether the user of the mobile computing device has permission to access the electronic device. Processing logic may also apply a notification rule to determine whether a user should be notified of the query. At block 530, processing logic may apply an additional rule to determine whether any instructions are to be sent to the mobile computing device.

At block 535, processing logic performs one or more actions based on an output from the rules engine. If the criteria of multiple rules are satisfied, then multiple different actions may be performed. For example, if a mobile computing device of a non-owner generated the query, then a first rule may cause a notification to be sent to the owner, and a second rule may cause a welcome message to be sent to the mobile computing device. In one embodiment, at block 540 processing logic sends a response to the mobile computing device with an indication of permissions. For example, processing logic may indicate whether the user of the mobile computing device has permission to access the low power electronic device, or if the user has permission to perform specific operations with regards to the low power electronic device (e.g., only has permission to send messages to the electronic device and display messages on the electronic device). The response may also include additional instructions, such as instructions to display a message on the mobile computing device, or instructions for the mobile computing device to send an instruction to the electronic device (e.g., to cause the electronic device to display a message). In one embodiment, at block 545 processing logic sends a notification to an owner of the electronic device. The notification may include an identity of the user, a location of the mobile computing device and/or the electronic device, etc. The location of the electronic device may be inferred based on the location of the mobile computing device and the known communication range of the low power radio signals broadcast by the low power electronic device in embodiments.
